What happened?
If you set up push notification as your preferred mode of sign-in, you will only receive the notification in your primary device, unless you manually specify your device on the sign-in page.
How to resolve this issue
You can change your primary and secondary devices in your OneAuth app:
- Open your OneAuth app, then tap Devices.
- Tap the device displayed under SECONDARY & RECOVERY DEVICES.
- Tap Make as Primary.
Selecting the device you have in your hand as the primary device may resolve your notifications related issues.
